please help me cause my ISP is not able to help me.
distro: mandrake 9.2

i am connecting to the internet through wireless card (z-com xi 626). everything was working perfectly until the day my ISP did upgrade of his network sw - winroute. win32 clients can still connect to his server flawlessly, this does not apply to my linux station though :(

i watched the net behaviour and here is what i got:
- right after boot process is finished (i turned off starting of dhcp client on boot) ifconfig -a command displays the information about two network devices (eth0 and lo - eth0 has zero values at all RX/TX items)
- i type ifup eth0 and using watch ifconfig -a command watch the changes:
* TX:1 RX:4
* TX:4 RX:2
* TX:10 RX:2
..
* TX:40 RX:5
then errors and dropped packets appear
* TX:42 RX:5 RX errors: 268
RX dropped packets and RX errors start to increase quickly (RX dropped = RX errors)

the new network device is created: eth0:9 with the same HW address as eth0 and with the following parameters:
inetadr: 127.255.255.255 vsesmer: 127.255.255.255 mask: 255.0.0.0

ifup eth0 command terminates with stdout: /sbin/ifup: line 433: 3012 Hangup /etc/init.d/tmdns reload >/dev/null 2>&1

i tried to connect with SuSE live CD (8.1) - unsuccessfully. ifconfig -a output:
